40. Shy Glizzy, 'Young Jefe'
Shy Glizzy has climbed to the top ranks of a conspicuously competitive D.C. scene, thanks in part to the national success of his hit record "Awwsome." His delivery shows a slight debt to Lil Wayne, yet where a rapper like Young Thug pushes his experimentalism further, Glizzy introduces restraint, tightening his voice into a consistent, piercing tone. His formulation of street rap is straightforward, even workmanlike, but at its most emotive — as on Percy Keith feature "Ungrateful" — it goes for the gut. D.D.
